The UCD team of agricultural scientists has been studying the proteins of Antarctic species for 11 years, starting in 1964. During the first seven years, trips were made each year to Antarctica to study and obtain specimens from penguins and cold-adapted fishes.

Air pollution poses a serious threat to the coniferous forests of California. Symptoms of air pollution damage to coniferous species have been observed in forests located north and east of the Los Angeles basin, east of major cities in the Central Valley, and east of San Diego. Damage is especially severe in the San Bernardino Mountains east of Los Angeles.

Harvesting onions for dehydration in California starts in the Palo Verde and Imperial Valleys in May or June, proceeds north, and terminates in the Tule Lake area in October or November. Consequently, processing plants do not operate from November to May. To keep costs at a minimum, it is important not to prepare and staff the plants before the onions will be available to dehydrate. Thus, the problem is to predict far enough in advance the time onions will be available, so that employees and onions can arrive at the processing plant at the same time.

Dilution of turkey semen to make it more fluid and easier to work with is practiced in some segments of the turkey breeding industry since fertility is not adversely affected and, in some cases, is enhanced. Dilution of semen also offers an economic advantage. The number of toms in a breeding flock, costing $30 each for the season, can be decreased. The potential savings to California turkey breeders from this reduction would amount to approximately $1.5 million for the turkey breeding season.

For many years, most lemon trees have been regularly pruned as a general practice. The reasons for pruning have included: ease of harvest and cultural operations, stimulation of fruit wood, andimprovement of fruit size and quality.
